Including uncertainty, calculate the expected resistance of an orange-green-red-gold resistor. 2. A student wires a circuit. When the power supply is switched on, the ammeter reads I = 60 mA and the voltmeter reads V = 4.5 V. a) Use Ohm’s law to calculate the resistance of the resistor being measured. b) What should the student set the voltage to so the current in the resistor is 0.05 A? c) Assuming the resistor has a 10% tolerance, what the color code?
